Just downloaded and installed the driver on a Dell Latitude CPx/J running 
1.5X. The chip is recognized and will output sound that is vaguely 
recognizable compared as to what it should sound like - very, very scratchy.

>From the kernel boot:

esa0 at pci0 dev 8 function 0: ESS Technology Inc Maestro 3 PCI Audio 
Accelerator (rev. 0x10)
esa0: interrupting at irq5
esa0: SigmaTel STAC9721/23 codec; 18 bit DAC, Rockwell 3D

FYI.
